E-Books →Inside ShellLite The Architecture of a Natural Language Programming System ShellLite, #1

This book documents the complete internal architecture of ShellLite as a case study in human-centered language design. You will explore how to:
Apply Cognitive Load Theory to syntax and language-design decisions
Build a Controlled Natural Language (CNL) that is readable yet unambiguous
Implement a full compiler pipeline: lexer → parser → AST → interpreter
Design forgiving parsers that ignore filler words and allow multiple phrasings
Bridge natural-language abstractions to low-level execution through FFI
Improve performance via source-to-source transpilation into host languages
Address the "Uncanny Valley" challenge that historically affected AppleScript and COBOL
Included in this work are:
A formal EBNF grammar specification, a full Python-based reference implementation, runtime architecture diagrams, performance benchmarks, and extensibility patterns applicable to any DSL project.
Perfect for:
learning compilers, designing DSLs, research in programming language design, and anyone interested in making code more human readable.
